The Keychain Access window showing certificates.

Keep your computer secure

To protect your computer, macOS uses digital certificates to verify the identity of the websites, servers, and other entities you communicate with. You can use Keychain Access to manage these certificates.

How to view certificates

You can find all your passwords, passkeys, and verification codes in the Passwords app on your Mac. See the Passwords User Guide.

To explore the Keychain Access User Guide, click Table of Contents at the top of the page, or enter a word or phrase in the search field.
